COMPOUND TOOL.

Application iiled November 23, 1922. Serial No. 602,862.

T all whom t may concern.'

Be it known that I, JOSEPH G. STEGH, a citizen of the United States, and a resident of Berwyn, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Compound Tools, of which the following is a specification.

My invention relates to compound tools for trimming down the burred ends of nipples or pipes, and has for its principal object the provision of a tool which will chamfer, ream, and square o' or finish the end of a nipple or pipe simultaneously and in a single operation.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1, is a view of my compound tool;

Fig. 2, is a longitudinal sectional view taken on line 2 2 of Fig. 1;

Figs. 3, 4, and 5 are detail views of the finishing, reaming and chamfering cutters, respectively Fig. 6, is an end view of the device;

Fig. 7, is a cross-sectional view taken on line 7-7 of Fig. 2;

Fig. 8, shows a nipple in the rough or uniinished State; and

Fig. 9, shows t-he nipple in its finished state, after the chamfering, reaming and 1inishing cutters have completed their work.

The form of my invention illustrated in the drawings comprises a circular body member or reaming head 12 tapering slightly toward the front and more abruptly toward the rea-r, substantially providing a beveled or reduced rear end 13, said tapering parts appearing in the form of two truncated cones joined at their bases. A threaded stem 14 extends from said beveled end 13 and is adapted to be engaged by a. suitable operating member (not shown) for supporting and rotating the device. Slots 15 and 16, extending longitudinally and diametrically of the reaming` head 12 and at right angles to `each other, are provided in the forward part ofsaid head, and a reamer or reaming cutter 17 is mounted in the central part of the larger slot, 15, while a cham- .tip 20 closely engaging the reamer 17, as

best seen in Figs. 2 and 3.

The cutting members 17, 18 and 19 extend 'substantially the entire length of the respective slots'15 and 16 and protrude from the front of therea-ming head, each being pro- Ivided with beveled cutting edges of suitable pitch, the reamer 17 having two tapering cutting edges and the chamfering cutters 18 having each one tapering cutting edge, as best seen in Figs. 2, 4, and 5. Suitable clearance is provided between the tapering cutting edges of members 17 and 13, as shown in the drawings, in order to produce properly trimmed nipple or pipe ends, as illustrated in Fig. 9.

A shell or sleeve 22 is provided to hold the cutters 17, 18 and 19 securely in position. This shell is mounted over the reamer head and its cutters with a driving fit, and hollow headed screws 23 are placed in screw openings provided in the rear part of said shell, and engage the beveled part 13 to hold said shell on the head and retain the cutters positively in position. Slots or notches 24 are cut in the wall of said shell or sleeve to furnish a toe-hold for a suitable punch or tool in order to force or drive said shell circumferentially on the head and loosen it for removal therefrom.

It becomes apparent from the above disclosure that the cutters may be removed to be sharpened or adjusted by loosening screws 23, tapping the shell with a suitable tool positioned in the slots 24 to rotate and remove said shell, and then lifting or driving the cutters out from their slots; and it is further apparent that said cutters may be t the device will simultaneously and speedily ream, Ghamfer, i and `square-'off or finisli the y endloawnipple or pipe.

Having described my invention, what I claim as .neivfandf desire tof secure by. Letters lPatent is: y

l. A tool comprising a reaming head tapering toward the front and rear and hav-V ing slots in the forward part, reaming, eliamfering and iinislnngcutters removably mounted V1n said slots substantially iilhng thelsame and extending forward therefrom,

a shell movable inaV lon'g'iti'i'idinal` direction Ion rsai'dfhead and fastening j'means rotatably lmounted in saidshell engaging thetrear tacutters.

g2. A' tool comprising -a reamingli'ead' tapei-ing vitorwa-rd and* rearward,VV and f having 'slots -in the' orwardfpart'whicli extend `longitudinally and diametrically'of said head and atfright angles to eachotherfreaming' and Vclian'ifering cutters'mounted in one slot and 'extendingflush with the circumference of vsa-i'd head, 'finishing cutters` mounted in the other 'slotfat rightl angles to 'saidla'tter slot,

a tapered shell driven over the forward tapering `part off said head,V said roaming and "chanifering cutters extending forward of said head and shell, and means on said shell movable into engagement with said rearward tapering part of the head for urging said shell in an axial direction on said head -and to :tasten and retain the elements in portion of the-"head orholding the shell in position, substai'itially as described.

In testimony whereofl have'signed my Vname to this specification jin the presence of:
